Synopsis
High pressure aloft and weak offshore flow will bring a warming
trend into Wednesday with gusty east winds near the coastal slopes
of the mountains for riverside and san diego counties. Onshore
flow will return for Thursday into Saturday. Night and morning
coastal low clouds will increase in coverage and spread farther
inland. Thursday will be 5 to 10 degrees cooler with slight
warming for Friday and Saturday. Offshore flow will strengthen on
Sunday into Monday, then slowly diminish on Monday night and
Tuesday with the stronger gusts on Monday to around 50 mph. High
pressure aloft combined with the offshore flow will bring a
warming trend for Sunday through Tuesday.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino
counties...

a weak trough of low pressure is moving through arizona early this
morning with surface high pressure over the great basin. This
will bring gusty east winds to the coastal slopes of the mountains
of riverside and san diego counties this morning of 30 mph or
less, diminishing during the afternoon with another round of
weaker and more localized winds in those locations for Wednesday
morning.

High pressure aloft and weak offshore flow will bring warming for
most areas today with not much change on Wednesday. Aircraft
soundings show weakening of the marine inversion with satellite
imagery showing patchy low clouds over the coastal waters
occasionally impinging on portions of the central and southern san
diego county coast.

A trough of low pressure off the west coast on Wednesday will move
inland through the western states on Thursday and Friday. For
southern california, this will bring a return of onshore flow on
Thursday spreading greater cooling inland with high temperatures
on Thursday 5 to 10 degrees cooler than on Wednesday. High
temperatures for Friday and Saturday will warm slightly and be
around average.

The marine layer will be in a slow deepening mode for Thursday and
Friday along with increasing coverage of night and morning
coastal low clouds. The low clouds are expected to spread into
portions of the western valleys on Wednesday night into Thursday
morning, and into portions of the inland valleys on Thursday
night into Friday morning. The marine layer will become shallower
during the weekend with patchier coverage of night and morning
coastal low clouds.

On Sunday, high pressure will strengthen off the west coast with
a strengthening trough of low pressure downstream over the
rockies. Surface high pressure over the great basin will bring
strengthening santa ana winds for Sunday into Monday with some
weakening on Tuesday. Model guidance continues to show the winds
peaking at moderate strength at most. While there are still some
timing differences among the models, it appears the winds will be
strongest for late Sunday night into Monday, with some weakening
for Monday night and Tuesday.

High pressure aloft off the west coast combined with the offshore
lower level flow will bring a warming trend for Sunday through
Tuesday.

Aviation
150915z... Coast... Patchy isolated low clouds with bases near 1500
feet msl through 15z. Any CIGS at any coastal airports would be
brief and intermittent. Patchy low clouds again after 04z tonight
with lower bases around 1000 feet msl. Otherwise clear with
unrestricted vis today and tonight.

Elsewhere... Wildfire smoke vcty ktrm today, otherwise clear with
unrestricted vis today and tonight.

Marine
No hazardous marine conditions are expected through Saturday.

Fire weather
Weak offshore flow will bring gusty east winds to the coastal
slopes of the mountains of riverside and san diego counties this
morning of 30 mph or less, diminishing during the afternoon with
another round of weaker and more localized winds in those
locations for Wednesday morning. Lowest daytime humidity will fall
to around 15 to 20 percent this afternoon for the inland valleys
onto the lower coastal mountain slopes. The humidity for the
valleys into the mountains on Wednesday is expected to be a
little lower but with weaker and more localized winds. This will
bring elevated fire weather conditions from the inland valleys
into the mountains for today and again on Wednesday.

Another round of stronger offshore flow is expected to develop on
Sunday, peak around late Sunday night into Monday, then weaken a
little for Monday night into Tuesday. This air mass with be drier
with lowest humidity on Sunday falling the 10 to 15 percent for
the mountains, deserts, and inland valleys, to around 10 percent
on Monday with a slight recovery on Tuesday. This will bring at
least elevated fire weather conditions for the inland valleys and
mountains on Sunday, with critical fire condition developing late
Sunday night and continuing through Monday. The strongest winds
are expected to be near the coastal slopes of the mountains and in
the inland empire below the cajon and banning passes.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
